Madeleine McCann investigation - what do we know now?

Thirteen years after the disappearance of Madeleine McCann, the truth of what happened on that fateful day in a Portuguese holiday resort remains unknown. Yet, in a dramatic turn of events, police revealed on Wednesday that a German suspect has been identified, as they offer a 10,000 euro reward for any information that helps solve this case once and for all.

ITV News correspondent Emma Murphy is live from Praia da Luz and former police officer Mark Williams-Thomas joins us with the latest.

What we know about the suspect

A German child sex offender may have kidnapped Madeleine McCann after breaking into her family's holiday apartment in Portugal, police have said.

The suspect, who has been named by British press but is protected by German privacy laws, is described as white with short blond hair, possibly fair, and about 6ft tall with a slim build at the time she vanished on May 3 2007.

Mr Hoppe said German police have not ruled out a sexual motive, but added that the suspect may have broken into an apartment in the Ocean Club complex in Praia da Luz - where Madeleine was on holiday with her parents, Kate and Gerry McCann, and her twin siblings Sean and Amelie - before spontaneously kidnapping her.

The suspect has been linked to an early 1980s VW T3 Westfalia camper van with a white upper body and yellow skirting, registered in Portugal - which was pictured in the Algarve in 2007, above.

Scotland Yard said he was driving the vehicle in the Praia da Luz area in the days before Madeleine's disappearance and is believed to have been living in it for days or weeks before and after May 3.

Detective Chief Inspector Mark Cranwell, said that he was taking the "really unusual" step of releasing two mobile phone numbers as part of the appeal.

The first, (+351) 912 730 680, is believed to have been used by the suspect and received a call from another Portuguese mobile, (+351) 916 510 683, while in the Praia da Luz area, starting at 7.32pm and ending at 8.02pm on the night of May 3 2007.
